I'm looking at replacing a custom ecommerce system for a UK business client with Shopify but although I've crawled through the forum and emailed Shopify support, I can't see how their tax calculation can be handled, and presumably this applies to loads of other UK and EU businesses.
The tax applied is dependant on the purchaser's BILLING address and the rules are
1. If the billing address is in the UK the tax is 20%.
2. If the billing address is in the UK and the client has provided a valid VAT number, there is no tax paid.
3. If the billing address is elsewhere in the world, no tax is paid.
Has anyone managed to handle this? And if so, how?
The idea scenario for me would just to be able to write a replacement tax calculation routine, but no idea if that is possible.
